Detection of buried Medium Voltage line

We are in one of those cases where the usual technology is not enough to geo-locate elements. In this case we have needed a detector DIGICAT_100, provided by the company INSTOP, which allows you to trace different types of conduits, such as power lines, which is what we have specified in this polygon.

It is as simple as tracing the area with this device and marking those points where DIGICAT indicates the maximum intensity. It is then geo-located with GPS, thus obtaining the situation with absolute coordinates.
